Oh no! We have new IP addresses. Part Trois By The Network Team. Why did you do this to me?. New IP addresses should provide enough addresses for whole herds of devices
By The Network Team
In the past, we asked that you add the new addresses whenever you move around the school as you help users and their machines.
Eventually, the older IP addresses will become unusable.
Also, some sites have had trouble when there was a mixture of old and new IP addresses.
Prior to this issue of IP addresses, your school had two types of IP addresses.
The public addresses were the numbers that were 66.4.X.X numbers and are visible to the outside world. Most schools have very few of these numbers. These numbers have been changed to 96.4.X.X.
The Private addresses were the numbers that are 10.x.x.x . Most of the computers in your school have these addresses.
Each school has at least four sets of 254 of these numbers.
An IP address consists of four sets of
numbers (octets) separated by a period.
An example of an IP address would be
Computers use IP addresses to help find where to send and receive data. Each computer must have a unique IP address.
-The new IP issue allows a huge number of IP addresses for each school. The first digits will always be 10.
-The second octet will be the school’s number that the BLTC was given
-The third octets vary from 7-111 based on what type class that the computer is in
-The fourth octet will be a number between
1 and 254.
The second digits (octets) are the numbers that are set up for each school
The School Number
10.xxx.7.1 Network use only
10.xxx.8.1 Nurses department only
10.xxx.9.1 Social workers only
10.xxx.10.1 DO NOT USE KNOX COUNTY uses this address range.
10.xxx.11.1 Special Ed administrative users only
10.xxx.12.1 Special Ed administrative users only
10.xxx.13.1 Administrative use only(For Administrators use at the schools)
10.xxx.14.1 Administrative use only(For Administrators use at the schools)
10.xxx.15.1 Technology staff use only
10.xxx.16.1 English as Second Language (ESL)
10.xxx.18.1 Food Service
10.xxx.19.1 Vision Specialists
The third digits are assigned for each department.
The Subnet Mask settings for this
range MUST be:
The Router (Gateway) address for these
IP addresses will be:
Where the xxx. is the school’s number
Some folks who have changed computers from the old 10.145.x.x addresses to the new 10.xxx.xxx.xxx addresses have found that they may have trouble printing to network printers that they used to be able to print to.
The problem of not being able to connect to printers and such would be an issue in the router.
The router provides all of the IP address information in the school in the form of files called Routing Tables.
When new Routing Tables were put into the router, the two routing tables (10.145.x.x and 10.x.x.x) were not linked together.
Routing and routing tables are handled by the fine engineers at ENA (Education Networks of America) in Nashville.
Some of our schools have the routing tables linked together and some do not. There is no way for the Network Team to do much about this but complain.
Be aware that when you change IP addresses on computers, you might also change the IP addresses on the printers too.
